How to unzip by code

What seems to be the problem, nobody is stopping you writing the program/code you want.

Use Google[^] to get ideas and start coding.
CP has this article DotNetZip[^] which explains how you can add unzip functionality to your application.

Once you have code and run into problems you can always come back here with a more specific question and the community will do its best to help you. Don't forget to post only the relevant code bits that pose the problem as a code dump is not usually helpful at all in getting someone to help/assist you.

Good luck and happy coding.
